On February 25th, Liu Jie, the chief physician and professor of dermatology at Peking Union Medical College Hospital, said that wearing a mask caused local skin pressure injury, which is a medical device-related injury, usually mainly in the nose, cheeks, palate, and auricle . She advises the public to choose a suitable mask to wear, such as a wide-sided mask with relatively low pressure, and can also choose to wear a lace instead of an ear-mounted mask. When wearing a mask, moderately change the position of wearing the mask every two to three hours to reduce the pressure. The mask has been repeatedly used for more than 6 hours. It is recommended to replace it. Preventive dressings can also be applied in advance on frequently stressed areas. (Edited by Zhou Yan)
